Is yours an automatic?

It is yea sorry forgot to mention! your's being a manual should be fine as long as the clutch is in good nick, no slipping etc..

I have manual S60 D3 from 2011 too. I quite like max torque low in the rev range (from 1500 rpm) on stock map. My only complain is that all fun ends after 3000 rpm. Did that change on yours after the remap? Do you have a power chart or something like that?

That can't change, that's a result of the small light pressure turbo. It has limits to how much air it can push. This doesn't bother me, an engine that can only rev to 3,500rpm is going to last a very long time.

Edit: The great thing about this engine and gearbox (manual) combination is the flexibility. 100-200 km/h achieved in 1,500rpm in 6th just as the turbo comes on boost. The remap I have is 470Nm torque which is sufficient to move the car at a reasonable rate. It's not the fastest car on the road, it does catch a few people out just how quickly it can move for something with a D3 badge.

Just get a BSR remap. They have been tuning Volvos for 30 years.
